Lamborghini debuted its newest ultra-lightweight speed demon in Geneva, revealing the Gallardo LP 570-4 Superleggera at a preview event on the eve of the auto show.

Clad in bright lime green paint and flanked by models, the Superleggera was the other big reveal for the Volkswagen Group family of brands--trailing only the show-stopping Porsche 918 Spyder Hybrid concept in attention.

The Superleggera cuts 154 pounds from the Gallardo LP 560-4 through extensive use of carbon fiber. It’s powered by a 5.2-liter V10 making 570 hp and can reach 62 mph in 3.4 seconds. Top speed is 202 mph.

“It’s about speed and power,” Lamborghini CEO Stephan Winkelmann said at the reveal.

The new Superleggera follows in the footsteps of its predecessor, which launched in 2007. It gets all-wheel drive and runs on 19-inch forged aluminum wheels wrapped in Pirellis.

Lamborghini says the Superleggera is the closest thing to a street-legal race car it makes and says it drew inspiration and technical development from its racing series, the Blancpain Super Trofeo.

Cutting weight has been a theme for Lamborghini as its engineers focus on ways to improve its potent supercars. The new version of the Murciélago LP 670-4 SV lost 220 pounds through extensive use of carbon fiber, while adding 30 hp.
